Sorry for no images. I just tried blowing out easter eggs with a bike pump. You only need one hole. Just use a pin to chip out a hole in the bottom of an egg. Take a needle valve (the kind you use to blow up basket balls etc.) and attach it to the bike pump/yoga ball pump. Hold the egg upright with the valve inserted vertically in the bottom of the egg. Pump gently and all the contents will come out (all over your hand). You can also use this for the traditional two hole method and not make quite so much mess.
